Open Imperium Galactica – Reimplementation of Imperium Galactica

Open Imperium Galactica

Open Imperium Galactica (Open-IG) is an open source Java re-implementation of the Digital Reality game Imperium Galactica, a real-time space strategy game released in 1997.

It has both the combat and resource management elements of a real-time strategy game and the vast research tree and colony-building aspects of traditional turn-based ‘space-empire-building’ 4X (eXpand, eXploit, eXplore, and eXterminate) games such as the Master of Orion series.

Open-IG attempts to reproduce the feel of the original game while fixing many bugs, inconsistencies and extending it with new features, however, it does not aim for producing an exact, behavior perfect and pixel perfect replica.

Features include:

Wide variety of gameplay including 4x galaxy management, city building, RTS battles in space and on land

Turn based

New building upgrade system which allows the player to meet demands (energy, food, etc.) even when the current planet has no more building space. Additionally, it fixes the issue with the random power-outputs of power plants: Open-IG uses a constant for power and upgrades multiply the output to meet the initial demands of the alien planets

Multiplayer support

Campaign editor

Supports big displays

OS

Notes

As this game is written in Java, it runs on a wide range of platforms. It's recommended your system has 3GB of RAM, with 2GB of disk space.
